Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA RECUPERACION DE CAFEINA DE UN CARBON ACTIVO CARGADO CON CAFEINA Y QUE SE CARACTERIZA PORQUE LA CAFEINA QUE DESTRUYE LA ACTIVIDAD DEL CARBON ACTIVO SE REDUCE ANTES O DESPUES DE CARGARLO CON CAFEINA. LLEGADOS A ESE PUNTO, EL CARBON ACTIVO SE PUEDE TRATAR CON ACIDOS, TAMPONADORES, AGENTES COMPLEJANTES, SUSTANCIAS DE REDOX, CAFEINA Y OTROS DERIVADOS DE LA XANTINA. LA CANTIDAD DE CAFEINA RECUPERADA PUEDE AUMENTAR CONSIDERABLEMENTE SEGUN ESTE PROCESO.
